A marchand balun design in ADS
I am just trying to replicate resistive network Marchand Balun as discussed in Analysis and Design of Impedance-Transforming Planar Marchand Baluns and 60GHz Balun Design chinese article in Keysight ADS software.
Note: For ADS user, simply replace your cell with resistive_network_marchand_balun and its resistive_network_marchand_balun.dds file
balun schematics
balun phase
balun insertion loss
balun return loss
TODO:
- Migrate the design to openEMS so that it could be reused in computer system without ADS software
- Layout of the improved marchand balun as discussed in MMIC Planar Spiral Balun Design using Keysight ADS
- Math derivation of the coupling factor, C
